題もあった。However, the decorative layer provided by the conventional spraying method or adhesive method, etc., may absorb moisture with the base material, such as a calcium silicate molded plate, or may differ in the amount of water absorbed or in the coefficient of thermal expansion. There was a problem in that the base material and the decorative layer peeled off when used. Furthermore, since conventional decorative boards are usually colored only on the surface, there are problems such as color unevenness occurring on the cross section when the end surface is exposed.

により得ることができる。This pressurized dehydration molding is carried out by a conventional drainage molding method, but it must be carried out so that the mica layer is integrally formed.Also, when forming mica layers on both sides of the substrate, a mixed slurry must be used. (A) is the mixed slurry described above again (
After adding B), gradually add the mixed slurry (A) to both sides of the layer of mixed slurry CB).
It can be obtained by forming a layer and then performing pressure dehydration molding.

コストの上昇などの問題が生ずる。By adding the latex, it is possible to improve the strength, tenacity (toughness) and processability of the molded product, but the amount added is 100 parts by weight of calcium silicate hydrate in terms of solid content. It is preferable to add 2 to 25 parts by weight.Increasing the amount added improves the strength of the molded product obtained, but on the other hand, problems such as a decrease in nonflammability, an increase in bulk specific gravity, and an increase in cost occur.
